A quick note for anyone preparing to use GMPartsDirect to order parts for their vehicle:
I've just discovered that they store passwords as plaintext. I used a different password from my other things (standard security practice), but I mutated it even further to put as much space between it and my other passwords as possible.
If you have an account there, do NOT use the same password you use everywhere else. Don't even use a slight variation (let's say your GMail is Password73, and your GMPartsDirect is 73Password). Use something entirely different, but yet still difficult to guess or brute-force. In the world we live in where people are constantly trying to crack sites, it's worth being extra careful if you know that site doesn't follow standard procedure and instead insist on storing passwords plaintext.
I'm not saying don't use the site - I have, it saved me a bundle, and they don't store payment info as far as I can tell. I mean, if you're trying to be extra careful, or it violates your personal security scheme, then you'd be better off staying away. Just be careful, and remember use a VERY unique password. No matter how badly you need your truck fixed, it's not worth having your online security compromised
